Fix "super" objects pretty printing in PyPy...

Fix "super" objects pretty printing in PyPy In PyPy there's no __self__ attribute for super(.) objects. As objects always have a __repr__, the found alternative was to use its curried argument. Previously, only the class name was verified as part of the result, now the tests include a regex.
